If you’ve ever seen a commercial-scale wind turbine in real life, then you’ll know that they’re huge – a single blade can be as long as 60 meters (197 feet). Researchers from Denmark’s Risoe DTU ...

The trailing edge of wind turbine blades can be manufactured in an elastic material that makes it possible to control the shape of the trailing edge. This will reduce the considerably dynamic loads ...

Risoe National Laboratory for Sustainable Energy, the Technical University of Denmark The idea dates back to 2003 when researchers from Risø DTU was inspired by the prey's ability to maneuver in ...

Risoe National Laboratory for Sustainable Energy, the Technical University of Denmark Today's wind turbine blades, which can measure more than 60 metres in length, are subjected to enormous loads, ...

Wing flaps are movable surfaces located on the trailing edge of the wings and are typically deployed during specific phases ...

ABSTRACT A mathematic rotating blade model is introduced in conjunction with periodic time-varying aerodynamic load, which is described by Beddoes-Leishman dynamic stall model. The consequent ...

Question: If flaps don’t increase lift, then why is a small amount of flaps used in soft-field takeoffs for some aircraft? Answer: Who said flaps don’t increase lift? Flaps do increase lift. Reference ...

Boeing plans to test and develop a trailing-edge variable camber (TEVC) system for the 787, which it says will reduce cruise drag and save the equivalent of 340-450kg (750-1,000lb) in weight. The ...

Differential flap settings and spoiler changes hold key for tackling hazard Researchers are planning flight tests of an Airbus A340-300 testbed in mid-2006 to evaluate the effect of differential flap ...

A flexible, controllable trailing edge for wind turbine blades has shown that it can reduce the loads on the turbine and in the end provide cheaper electricity from wind power. The idea dates back to ...
